As shown in the figure,a person standing on the floor pulls on a rope with a force F at an angle of (with respect to the positive x axis)in order to raise a weight with pulleys.It is raised at a constant velocity.Consider the rope as massless and the pulleys as frictionless.(The mass hanging from the lower pulley does not interfere with the movement of the pulley.)If the maximum tension the rope can withstand without is 100 N,what is the largest weight this pulley system can lift (within 5% accuracy)?
A)50 N
B)200 N
C)100 N
D)141 N
E)71 N
